RIP configuration

router rip
network
=>enable routing protocol RIP version 1 (classful, same subnet used throughout whole network)
=> routing table send out thru broadcast address 255.255.255.255


router rip
version 2
network

=>enable routing protocol RIP version 2 (classless, able to used different subnet VLSM)
=> routing table send out thru multicast address 224.0.0.9, UDP Port number 520
no auto-summary => no auto summarization

default-information originate => generate a default route into RIP

passive-interface fa0/0 => prevent routing update out thru interface fa0/0

Load Balancing

maximum-paths

=> default 4, maximum 6

=> IOS version 12.3 onwards up to 16

By default, RIP uses broadcast or multicast to push out routing table. If there's a need, we can push update using unicast neighbor 

Juniper

R2#set protocol rip group RIPGROUP2 neighbor em2.0

R3#set protocol rip group RIPGROUP3 neighbor em2.0

Group name is local significant

Be default Junos dont advertise route, need to create a policy

R2#set policy-options policy-statement RPOLICY term 1 from protocol rip

R2#set policy-options policy-statement RPOLICY term 1 from protocol direct

R2#set policy-options policy-statement RPOLICY term 1 then accept

R2#set protocol rip group RIPGROUP2 export RPOLICY

R3#set policy-options policy-statement RPOLICY term 1 from protocol rip

R3#set policy-options policy-statement RPOLICY term 1 from protocol direct

R3#set policy-options policy-statement RPOLICY term 1 then accept

R3#set protocol rip group RIPGROUP3 export RPOLICY
